To all wlmm t may concern:

Be it known that l, DoMnNrco MAnnAzzo, a subject of the King of ltaly, residin at Brooklyn, in the county of Kings and tate 5 of New York, have invented new and useful w' object to provide a device which is light and compact in const-ructionand which may he readily placed in the pocket of the user for transportation.

' Another object of the invention is to pro l@ vide a fan having foldable blades arranged in such a manner that when not in use the device may be stored 1in a mlnlmum amount of space.

,L As a further object the invention contem- 29 vlates the provision of blades having stops 5/ position, and as soon as thel operation ceases preferably cut on the inside 'of the gear 22 provide d thereon 1n such a manner as to cause fan.' Showing the Figure 2 is a face view of Figui-e1, show,

arranged thereon for automatically limiting the movement cfsaid blades in such a manner that as soon as power is applied to the device the blades will be thrown to open the blades willautomatically fold.

` Still another object vof the invention is to gear train having a clutch arran the blades to rotate in one direction.

ith these and other objects in view the invention consists in the novel conmruction, combination and arrangement of parts which will be .fully set forth in the following specification, claimed and illustrated in the accompanying drawing, in whicln v- Figure 1 is a side view of this improved blades in folded position,

ing the blades inopen position,

Figure 3 is an edge view of the interior mechanim, l

ltigure e is a Af view of Figure 3,

Figure 5 is a bottom plan viewof Fig'- ure 3, f

Figure 6 is a fraentary f view of the xed blade,

Fi 7 is aview similar to Figure 6 of one ci? the loldable blades, and

Figure 8 is a view silar to Figure 7 ot the other foldable blade.-

Referring to the drawings in detail, the numeral 10 designates a hollow housing ha.' .f a slot 11 in ite upwr side for the acn blades are 'enged commodation of the reciprocating plunger of the actuating mechanism. As illustrated-in the drawings, the housing is hollow and circular in formation and is of sumcient size to contain the mechanism illustrated in Figures` 3 to 5.

n The actuatingmechanism above` referred tol comprises a base plate 12, provided on one face with a longitudinal guide 13 over which` the lll-shaped plunger 14 is ada toslide. Extending laterally from the hase plate 12 is anarm 15 which is pie :4

receive the end of a shaft 16, the opposite l end of which is rotatably received in an arm 17 formed on.. the cover,plate'l8 which is attached by suitable securing means such as screws 19 to the guide 16, and serves to retain the plunger 14. in proper position. Formed along one of the marginal edges of the plunger 1d is a plurality of rack teeth 20 which mesh with a pinion 21 which is loosely mounted on the shaft 16 and is arranged by means of a suitable clutch mechanism to drive a gear 22 in one direction. l

Said clutch comprises the ratchet' teeth d5,

and a suitable ratchet pawl 46, mounted-on to original positon and owing to the clutch arrangement the pawl 46, slipsl over the ratchet teethd within the gear 22 and the pinion21 may .freely rotate in the reverse direction 'thout driving the r.

The tanconsists oi a huh 27 which is arv ran ed to he .secured to the outer end ot shalt 2d as shown in Fires land 2, d this huh `is providedwit` a pair of plates Mil 28 between which/the huh members ol the 'i A. Ie 0. 29 i9 feed on one of. the plat/m28 and is adept- .ed to 'he-bent' into the ition illustrated in Figure l so as to pass through the. notch 30 or the huh member 31 on the station tan hlade 32 and it w thus he n thaty l blade 34 is provided with an arcuate'recess which yforms stops 36A and 37 which are adapted to be engaged by the ton e -291 when thedevice is set in operation. similar arcuate cutawayy portion BS-"orming stops 39 and 40 are arranged on the hu member of the fan blade 41. It will thus be seen that the fan blades may be folded into the position illustrated in Figure 1 when the device is at rest but as -soon as the device is set in Amotion it will be obvious that the tongue 29 will move in the recesses 35 and 38 respectively, until it enea s the slots 37 and 40 respectively, a-twlciic the fan blades will have' assumed the position illustrated in Fi re 2. While in the foregoing thereA has' n shown and described the 'preferred embodiment of this invention, it is to be understood that certainminor'changes, in the details of construction, combination and arra ement of arts may beresorted to without e-l partingl rom the spirit and scope of the invention as claime ,cover l. ln a rotary hand fan, a centrally slotted reciprocating plunger, rack teeth formed on one edge of said plunger, a base plate, an arm extending horizontally from said .base plate substantiall midway between theends thereof, an shaped cover plate, a leg 0,11 Said cover plate substantially parallel to and disposed oppositely to'said arm of said base plate, a second leg on said V of screws passing time v connected to said shaft said driving means between said plate ina plane in spaced- ,relationl t v larsneoA nalled in said arm' and saidsecond leg near plate near the bend thereof and in said base plate, a guide arranged inthe slot of said plunger and between said second leg of said cover plate and vsaid base plate, and a air.
